Abstract
Description
Technical Field
[0001] This utility model relates to a support base for a switch machine, specifically a vibration damping base for a switch machine support. Background Technology
[0002] For the support plate of the switch machine, it is usually supported by the support base. The existing support base is basically a rigid connection. This connection method cannot dampen vibration. In order to achieve the function of damping vibration, rubber damping pads were gradually added to the upper and lower ends of the support base to achieve the effect of damping vibration. Although this method achieves the function of damping vibration, practical tests have proven that this method not only has a poor damping effect, but also has the problem of decreased damping function due to rubber aging. In addition, the height range that can be adjusted is very limited. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a switch machine support vibration damping seat with good shock absorption effect, high durability and adaptability to a wide height range.
[0004] To solve the above-mentioned technical problems, the present invention provides a switch machine support vibration damping seat, comprising a base, a support sleeve fixedly installed on the base, a support bolt that can be screwed into the support sleeve, and a support spring for being fitted onto the support bolt. The support bolt is also fitted with an upper top cover located at the top of the support spring and a lower top plate located at the bottom of the support spring. A locking element that presses against the bottom of the lower top plate is also screwed onto the support bolt. After the support bolt passes through the support plate on the switch machine, the top cover, the support spring, and the lower top plate are fitted onto it in sequence, and after the locking element is screwed on, it is screwed into the support sleeve, thereby enabling vibration damping through the floating of the support spring.
[0005] The top cover is a sleeve with a through hole, and the support spring is placed in the inner cavity of the sleeve.
[0006] A rubber pad is placed between the top cover and the support plate.
[0007] A locking nut is screwed onto the support bolt, located above the support sleeve.
[0008] An elastic washer is pressed between the support sleeve and the locking nut.
[0009] The locking components are two locking nuts screwed onto the support bolts to lock the position of the lower top plate.
[0010] The base is a bowl-shaped structure with a central hole. The bottom of the support sleeve is provided with a threaded connection section. The threaded section of the support sleeve passes through the central hole and is fixed by screwing on a base nut.
[0011] The bottom of the base is equipped with vibration damping pads.
[0012] The upper half of the inner cavity of the support sleeve is provided with an internal thread for engaging with the support bolt.
[0013] The advantages of this utility model are: (1) By setting up a shock absorption system consisting of support bolts, top cover, support spring, bottom plate and support sleeve, shock absorption can be achieved by the floating of the support spring in the shock absorption system. On the one hand, the shock absorption effect is better by using the elastic force of the support spring, and there is no need to rely on rubber shock absorption. It also effectively avoids the problem of reduced shock absorption function due to rubber aging, and has good durability.
[0014] (2) By using the support sleeve and the support bolt that can be screwed into the support sleeve as the main support components, it can be adapted to the vibration reduction of the switch machine support plate with a large height range. If the height is particularly high, the support bolt with a longer length can be directly replaced. Other parts do not need to be replaced, and it can adapt to a wider height range.
[0015] (3) The locking nut screwed onto the support bolt and located above the support sleeve, along with the elastic washer pressed between the support sleeve and the locking nut, can effectively prevent the support bolt and the support sleeve from slipping and lock. Attached Figure Description

Figure 4 This is a cross-sectional structural diagram of the vibration damping seat for the switch machine support of this utility model. Detailed Implementation
[0017] The vibration damping seat of the switch machine support of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0018] As shown in the figure, the vibration damping seat for a switch machine support of this utility model includes a base 1, a support sleeve 2 fixedly installed on the base, a support bolt (specifically an external hexagonal bolt) 3 that can be screwed into the support sleeve, and a support spring 4 for mounting on the support bolt. The base 1 is a bowl-shaped structure with a central hole. A vibration damping pad 13 is installed at the bottom of the base 1. The support sleeve 2 is a support sleeve that is open at the top and closed at the bottom. The inner cavity of the support sleeve has an internal thread for screwing into the support bolt, and a threaded connection section is machined at the bottom of the support sleeve. The threaded section of the support sleeve 2 passes through the central hole and is fixed by a base nut 12. Figure 4 As can be seen, when the support sleeve 2 is fixedly installed with the base, a base spring washer 14 located above the base nut 12 and a retaining spring 15 located below the base nut 12 are also installed on the threaded section. The support bolt 3 is also fitted with an upper top cover 5 located at the top of the support spring 4 and a lower top plate 6 located at the bottom of the support spring. The upper top cover 5 is a sleeve with a through hole. The support spring 4 is placed inside the sleeve. The area of the lower top plate 6 is smaller than the inner diameter of the sleeve but larger than the diameter of the support spring. This allows for both limiting the position of the support spring and providing support for its movement. Within the operating range, a locking element 7 is screwed onto the support bolt 3 and pressed against the bottom of the lower top plate. After the support bolt 3 passes through the support plate 8, which serves as a bracket on the switch machine, the top cover 5, the support spring 4, and the lower top plate 6 are sequentially fitted on it. After the locking element 7 is screwed on, it is screwed into the support threaded sleeve 2. Of course, in order to ensure the reliability of use, a rubber pad 9 is placed between the upper top cover 5 and the support plate 8. At the same time, a locking nut 10 located above the support threaded sleeve 2 is screwed onto the support bolt 3. Through this structural design, the purpose of shock absorption is achieved by the floating of the support spring 4.
[0019] Furthermore, an elastic washer 11 is pressed between the support sleeve 2 and the locking nut 10.
[0020] Furthermore, the locking component 7 consists of two locking nuts screwed onto the support bolt to lock the position of the lower top plate. Two locking nuts are used for locking, but anti-loosening nuts or side-locking anti-reverse nuts can also be used for locking. It is mainly used to prevent the spring from retracting and locking the stressed part of the support spring.
[0021] Furthermore, an internal thread for engaging with the support bolt can be provided in the upper half of the inner cavity of the support sleeve 2, which is easy to process and makes screwing easier.
[0022] The installation process is as follows: (1) First, place all the accessories (external hex bolts, support springs 4, base 1, vibration damping pads, lock nuts, locking nuts 10, support threaded sleeves 2, elastic washers 11, and upper top cover 5 and lower top plate 6, etc.) into the bottom of the support plate of the switch machine in sequence; (2) From the external hex bolt, pass through the switch machine's support plate, rubber pad 9, upper top cover 5, support spring 4, lower top plate 6, lock nut, locking nut 10, elastic washer 11 in sequence as shown in the diagram until the support screw sleeve 2; (3) Adjust the locking part 7 to adjust the supporting force of the support spring to a suitable elastic force (the appropriate elastic force is when the outer circle of the top plate 6 is submerged to half of the lower edge of the top cover by the elastic force calculation). (4) Tighten the locking nut 10 to make the locking nut, the upper elastic washer 11 and the support sleeve 2 into a whole; (5) Finally, the threaded section of the support sleeve 2 is passed through the center hole and the base nut 12 is used to cooperate with the base spring washer 14 and the snap ring 15 to fix the base to the bottom of the support sleeve.
[0023] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
